Serial No. 389,301'.

My present invention relates to building materials and more particularlyto a prepared building material made ready to apply as an insulation forwalls, ceilings, and floors, land it has for its object to prvide animproved article of this naturewhich will lend itself in a peculiarlyadvantageous manner to the manipulations of the user in applying it, andat the same time provide an improved insulation medium particularlyagainst the entrance or escape of heat and cold.

,T To these and other ends the invention resides in certain improvementsand combina- .tions of parts, all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the'end of the specification.

In the drawing:

Fig. 1 is a fragmentary longitudinal central sectional view through aformin machine illustrating the manner in whic my improved insulatingmaterial is produced;

Fig. 2 is an enlarged transverse sectional view through a strip of thematerial in its normal condition;

Fig. 3 is a view similar to Fig. 2 showing the strip bent transverselyto conform to its intended position between the oists of a ceiling orfloor or between the stu ding strips of so a wall;

Fig. 4 is a further fragmentary sectional view showing the material ofmy invention bent and secured in place between 'thestud ding strips of awall, and Fig. 5 is a similar view showing two companion strips of thematerial similarly laced in a dilerent manner between a plura 'ty ofadjacent studding strips.

Similar reference numerals throughout the several views indicate thesame parts.

Referring first to Fig. 2 of the. drawing,

there is there shown, as before stated, a transf verse section of astrip of insulating material constructed in accordance with andillustrating one embodimentof my invention. It comprises a filler orinterior body portion 1 zoi? a flocculent fibrous material such as hair,cotton or an appropriate one of the substances usually employed in themaking of 5o carpet linings and building materials of this generalnature. I prefer to employ a mixture of short cotton ibers or cottonwaste and jute, but this selection is immaterial to the objects of thepresent invention.

The interior body is faced and coniined on both sides by liners 2l and 3which have considerable tensile strength and may bel composed, andpreferablyare composed of paper. The central portion of the strip isrelatively thick and fluffy but the longitudinal edge portions indicatedgenerally at 4 are relatively thin or compressed as clearly shown inFig. 2. This thin edge may be produced by using less of theiiller stockat these points or by compacting the stock or both. I prefer, in anyevent, to compact the filler stock at the edges by compressing andsewing the liners 2 and 3 together in this region as indicated at 5. Ifurther refer to first confine the said longitudinal e ges 4 of the batbetween paper or similar strips 6 arranged on opposite sides and throughwhich the line of stitching 5 is made. The liners 2 and 3 are laterpasted thereon with an adhesive that secures the stitches to the strips6 and prevents the bat from later expanding at these edge portions.There is thus produced a permanent thin edge portion with a f softandexpandable center portion.

This insulating bat or strip as described and as essentially shown inFig. 2 may, with the changes hereinafter described, be produced on amachine of the nature of and in accordance with the general method setorth in my prior Patent No. 1,713,309, of May 14, 1929. I ,have shownthe essential and modified element of this machine in Fig. 1, referringto which 1 indicates thel bat alone suitably formed and traveling ontables 7 and 8 in the direction of the arrows between presser rolls 9.i/(n apron conveyer traveling over the table and around the appropriaterolls 10, 11, and 12 is shown at 13. The strips 6 are fed on to the batat its edges and under the guide rolls 14. They thence pass to theneedles 15 of the sewing machine which form the stitching 5. Actlng inconjunction with these needles (there being of course a plurality of4the same) are presser feet 16 in the manner of an ordinary 100 sewingmachine. The action-of these presser feet, acting in the ordinarymanner, presses the bat 1 and the reinforcing strips 6 to a suficientdegree to produce the desired relative thinness and compactnessat theedges of the bat, and the stitching extending through the strips 6 andthe filling between them holds the filling in this relatively thincondition, resisting any tendency for it to spring back to its originalthickness. If necessary an additionalcompression device,

acting ahead of the needles may be provided 1n theV form lof springpressed rollers 17. After vthe reinforcing strips 6 have been appliedand stitched to the filling, the liner sheets 2 and 3 may be applied tothe top and bottom of the bat in any suitable manner, such as by thesame mechanism shown in said prior Patent No. V1,713,309forapplying theliner sheets 5 and 5a. The utility of a thin edgedlinsulating stripformed and constituted as described maybe explained as follows:

In Fig. 4A indicates adjacent studdings 0f a wall in horizontalsectionand B indicates lsheathing applied thereto. The lath air spaces Fbetween it and the sheathing and air spaces G on the opposite sidesbetween it and the interior finish or wall forming elements4 C and D.Thus two separate airy spaces are provided instead of one which,

as anyone skilled in the art will see, adds greatly to theinsulatingqualities from this standpoint alone.

But in addition to this the flexing of the insulating strip to thisposition with its edges so compressed and confined contributes anotherinsulating factor. This resides in the expansion of the fibrous body 1at the center, as shown in Figs. 3 and 4, which results from the fact ofthe bending of the material while the edges are held fast in theircompressed condition.;\Were they not so held fast the insulating stripwould not accommodate itself to the position shown but would have atendency to crinkle or break indiscriminately throughouty its width andthere would be a further tendency for it to expand and pull away fromthe liners at the edges where it must be fastened instead of expandingas aforesaid at the center where such expansion adds to its lnsulatmgqualities.

In Fig. 5 the same 'action is shown Where product being compressedthroughout a substantial width to a greater degree than intermediateportions thereof.

2. A padded product for the insulation of the walls of buildings andsimilar purposes which comprises in combination an inner flocculent massof fibrous material confined between liner sheets having relativelygreater tensile strength, the longitudinal edges of the product beingcompressed to a greater degree than intermediate portions thereof andbeing secured in such compressed state of lines of lstitching extendingthrough said fibrous material.

3. A padded product for the insulation of the walls of buildings andsimilar purposes which comprises in combination an inner occulent massof fibrous material confined between liner sheets having relativelygreater tensile strength, the longitudinal edges of the product beingcompressed to a greater del ree than intermediate portions thereof andeing secured in such compressed state by lines of stitching, the linesof stitching passing through reinforcing strips extending along saidlongitudinal edges.'
